Enum Constant Detail

Insert

public static final TxKind Insert

Changes apply to SQL Insert.

InsertUpdate

public static final TxKind InsertUpdate

Changes apply to SQL Update.

This state exists exclusively during a live transaction and within a TxScope.ScopeConsumer when an entity is Inserted via CRUD and then further modified via CRUD after the Insert. Such modifications are persisted via Update.

Example:

 Sakila.commit(ctx -> {
   Film film = Film...build(); // txbindings state is now Insert
   film.setRating(...);
   List<Film> films = Film.fetch(...); // query triggers prior CRUD to persist, INSERT film
   film.setDescription(...); // txbindings state is now InsertUpdate
   film.setSomethingElse(...);
   List<Inventory> inv = Inventory.fetc(...); // query triggers prior CRUD to persist, UPDATE film
   ...
 });
 
 

Update

public static final TxKind Update

Changes apply to SQL Update.

Unknown

public static final TxKind Unknown

Method Detail

values

public static TxKind[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (TxKind c : TxKind.values())

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static TxKind valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:
